This page contains information explaining how to upgrade Fedora using yum.

Although upgrades with yum have been tested and work, live upgrades are not recommended by the Fedora Project. If you are not prepared to resolve issues on your own if things break, you should probably use the recommended installation methods instead.

The recommended installation method is with a boot media with the Anaconda installer as detailed in the Installation Guide. PreUpgrade is a slightly different upgrade method where the all packages are downloaded before the system is rebooted into the Anaconda installer.

When upgrading with yum you don't get any help from Anaconda, but if you are lucky you might be able to upgrade systems remotely over ssh and with limited downtime. (You will still need to reboot to get the new kernel and system libraries/services running) Rebooting after such an upgrade is always very exciting.

A live upgrade with yum usually works well with a typical installation and when following the advice below.

Participate

If you are upgrading using Yum and it shows up any general dependency issues, please file them in http://bugzilla.redhat.com. But please read this page and all references pages and search the mailing list archives before filing bugs. And of course, please help keeping this page updated.

2. Clean Stuff

Review and remove all .rpmsave and .rpmnew files before and after upgrading. (And if you have selinux enabled then remember to check security context if you move config files around.)

Find unused config filesMerge and resolve the changes found by the following script: for a in $(find /etc /var -name '*.rpm?*'); do diff -u $a ${a%.rpm?*}; done.

Now is a good time to remove packages you don't use - especially non-standard packages.

Find and review "unused" packagesYou can find packages not required by other packages with the tool package-cleanup from the yum-utils package: yum install yum-utils; package-cleanup --leaves. These packages could be candidates for removal, but check if you use them directly or if they are used by applications not backed by rpm packages. Remove them with yum remove package-name-and-version.
Another useful tool for cleaning up unused packages is rpmreaper. It's an ncurses application that lets you view rpm dependency graph and mark packages for deletion. Marking one package can make other packages leaf, which you can see immediately, so you don't have to run the tool several times to get rid of whole sub-tree of unused packages. Install with: yum install rpmreaper.

Find and review "lost" packagesYou can find orphaned packages (ie packages not in the repositories anymore) with: package-cleanup --orphans. This will also show packages which have been partially uninstalled but where the "%postun" script failed.

Make sure you have the yum-fastestmirror package installed so that yum uses the "best" mirror.

yum install yum-fastestmirror

Then remove all traces of the version you are leaving from the yum cache in /var/cache/yum.

Note: Some users have reported that attempting to download through rpm returns a response 550 and "transfer failed" messages. If this is the case, you can download the rpms and install locally. Consider:

If you have 3rd party repositories configured, you may need to adjust them for the new Fedora version. If you switch from one Fedora release to another there is often nothing that needs to be done. If you switch to Rawhide from a standard Fedora release (or vice versa) then you most of the time need to install the Rawhide release RPMs from the 3rd party repository as well (or the standard ones, if switching back).

Note that the upgrade is likely to fail if there are outdated dependencies from packages not backed by a yum repository or backed by a repository which isn't ready for the new version.

4. Do the upgrade

If using selinux make sure it is in permissive mode - neither disabled nor enforcing.

It is a good idea to do the upgrade outside the graphical environment. Log out of your graphical desktop and then go to a text console

ctrl + alt + F2

log in as root, and go into runlevel 3

telinit 3

Once a live upgrade is started do not stop the upgrade by rebooting, killing the process, or by any other method until it is complete, doing so will cause the affected system to be in a mixed state. Partially the old release and partially the new release. In this state the system will not be reliable and will not operate as expected. The only way to recover from this is to reinstall if it occurs.

Update important packages firstYou can start try to update the update machinery first with yum update rpm\* yum\*. Another idea is to start with glibc. In both cases dependencies might however expand it to an almost full upgrade anyway. And doing a full upgrade might be more safe. YMMV. (In particular, do not upgrade rpm and yum separately if upgrading to a system with a different version of python e.g. 2.4 to 2.5.)

Upgrade all packages with

yum upgrade

yum might complain about conflicts or requirements. That is probably because you have used non-standard repositories or installed non-standard packages manually. Try to guess which packages cause the problem (or at least is a part of the dependency chain) - uninstall them and try again. Remember to install the packages again if they are essential.

Ensure that all (new) essential packages from the new version is installed with

Version specific notes

From pre-release

Fedora 11 -> Fedora 12

All Fedora 12 RPM packages use XZ/LZMA compression, which is only supported by the rpm-4.7.1-1 update (or later) for Fedora 11. Before upgrading from Fedora 11, run yum update rpm.

It is not possible to update directly from Fedora 10 or earlier with yum. To upgrade from Fedora 10, first update to Fedora 11, and then upgrade from Fedora 11 to Fedora 12. If you are using a release before Fedora 10, use one of the official upgrade methods or backup your data, perform a fresh installation, and restore from backup.

Upgrades from Fedora 11 might currently fail with missing dependencies (for example related to totem-gstreamer or PolicyKit-kde). The dependencies are ok, but Fedora 11 yum has problems resolving them (bug 519172).

If your root filesystem does not mount with 'defaults' options, you will need to add the root filesystem's mount options to grub.conf with the kernel flag rootflags - initramfs does not pick up the options the way initrd used to. e.g. if you mount your root with the flags data=journal,relatime then you would add to the end of the 'kernel' line in grub.conf: rootflags=data=journal,relatime . After updating to dracut-004-4.fc12 or later, this kernel flag can be removed.

Fedora 10 -> Fedora 11

It is only possible to upgrade to Fedora 11 from an updated Fedora 10. Older systems must be upgraded to Fedora 10 first. The RPM format has been changed for Fedora 11, so the older rpmlib must be updated first. Otherwise the process will fail with rpmlib(FileDigests) dependency problems. Support for the new format has been backported to Fedora 10 in an update.

yum update rpm

New initrd built when installing a new kernel while running Fedora 10 might fail. To solve that boot with an old kernel (to get the new userspace) and (re)install the new kernel.

Systems with PAE support (indicated by pae in /proc/cpuinfo) should use kernel-PAE.i686. The new kernel must be changed/installed manually: Set DEFAULTKERNEL=kernel-PAE in /etc/sysconfig/kernel and yum install kernel-PAE. Refer to Dave Jones' blog post for details.

The yum update step should NOT be run inside a gnome desktop session/gnome-terminal. 494046 could result in a unusable install when gnome-terminal segfaults during the upgrade. Update should be run in a vty, runlevel 3, or a screen session.

fedora-release-11-1.noarch changes the yum mirrorlist URL so that it uses a "metalink", but the version of yum currently in F10 doesn't understand this syntax, leading to yum downloads failing with this error message:

YumRepo Error: All mirror URLs are not using ftp, http[s] or file.
Eg. </metalink>/

Some packages in Fedora 10 are regarded as newer than those supplied by Fedora 11 and its updates repository. These include ntpd, ntpdate (506040, 504980), unique, unique-devel, eclipse-changelog, eclipse-svnkit and svnkit. You may wish to remove these before performing the upgrade, then reinstall them afterwards. Doing so may require --nodeps.

Some i386 packages in Fedora 10 are replaced with i586, i686 or x86_64 packages in Fedora 11. These include gpm.i386, glibc-2.9-3.i386. You may wish to remove these before performing the upgrade, then reinstall them afterwards. Doing so may require --nodeps.

mplayer-1.0-0.104.20090204svn.fc10 from the RPM Fusion repository has a dependency on libfaad.so.0 that the depsolve doesn't find, but rpm_check_debug does. You may wish to remove mplayer before performing the upgrade, then reinstall them afterwards. Doing so may require --nodeps.

anaconda by default now refers to encrypted devices by UUID, not by device name, to better handle device name changes. An encrypted device using partition /dev/sda1 with UUID 12345678-1234-1234-1234-123456789012 would now be called /dev/mapper/luks-12345678-1234-1234-1234-123456789012 instead of /dev/mapper/luks-sda1. You may wish to make the same changes on your system on upgrade; if you do, make sure to run mkinitrd afterwards.

If you use non-root encrypted devices, you will need to re-run mkinitrd for any older kernels that you want to still boot on the system.

If you are upgrading to Fedora 9 and use emacs, you must upgrade to the latest version of emacs for your prior release to ensure a clean upgrade. Fedora 8 users must have emacs-22.1-10.fc8 or later, while Fedora 7 users must have emacs-22.1-7.fc7. Bug report here.

Due to the switch from sysvinit to Upstart , it is recommended that users who do an upgrade on a live filesystem to Fedora 9 reboot soon afterwards. If you do not reboot, you may want to take careful note of any '/etc/inittab.rpmsave' or '/etc/inittab.rpmnew' files. When rebooting after an upgrade then be aware that sysvinit that was used to start the system can't be used to shut it down.

Various other packages including Beryl are no longer in F8 and not obsoleted:

yum erase beryl\*

Fedora Core 6 -> Fedora 7

Fedora 7 replaces the old IDE subsystem with libata. Drive device names which previously started /dev/hd.. will become /dev/sd.. after the upgrade. /dev/hda1 will usually become /dev/sda1, although there may not be a direct relationship between the old and new device names (for example hdd does not necessarily become sdd). Before you reboot be sure to change all references to /dev/hd.. in your config, especially /etc/fstab - where it however may be simpler to refer to filesystems by label (check out the programs blkid, tune2fs, and mlabel). LVM Volume names are not affected. In /boot/grub/device.map change /dev/hd.. to /dev/sd.. before running grub-install - and don't change (hd0). Changing /boot/grub/grub.conf may also be required.

The libata layer represents all hard disks as SCSI disks, which are limited to 15 partitions in the kernel. IDE hard disks with more than 15 partitions are not supported in Fedora 7.

On a system which has been upgraded from releases prior to FC6 you may need to remove up2date and rhnlib rpm -e rhnlib up2date

If you see the message package gpm-1.20.1-84.fc6 (which is newer than gpm-1.20.1-83.fc7) is already installed when performing a yum update uninstall and reinstall the gpm package.

If you had installed Suns jre it might be removed during upgrade. Be aware that jre-6u1/jre-1.6.0_01-fcs requires compat-libstdc++-33.

If you get Error: Missing Dependency: python(abi) = 2.4 is needed by package libxml2-python and/or Error: Missing Dependency: python(abi) = 2.4 is needed by package rpm-python during your yum upgrade ensure you have done a yum clean all and check that both the base and updates repositories are available from your mirror. You will need the updates repo for the upgrade to succeed.

Since Fedora Core 6 uses python 2.4 and Fedora 7 uses python 2.5, do not try and run yum upgrade yum\* rpm\* before upgrading everything else - this succeeds but leaves yum in an unusable state.

Fedora Core 5 -> Fedora Core 6

After upgrading, you cannot use the DVD ISO loopback mounted as a repository directly (e.g. no baseurl=file:///mnt/fc6/) because the repodata files contain URLs of type media:// which yum can't handle. You can use the loopback-mounted DVD for the initial upgrade from FC5 -> FC6, just not thereafter. After removing the baseurl=file:/// option from your fedora-core.repo file, remember to yum clean all.

Fedora Core 4 -> Fedora Core 5

Before upgrading update your kernel first.

Make sure you have the latest kernel ABOVE 2.6.14 and uninstall all kernel versions before it, otherwise initscripts and a few other packages will conflict and prevent the ugprade. Use something like the command below

Once you have updated, run: yum groupinstall "GNOME Desktop Environment" (change GNOME to KDE if appropriate). That'll get you some new packages that were added in FC4 like Evince and NetworkManager.

Some new groups were added - yum grouplist - check out Eclipse and Java Development in particular.

Problems:

Postgres database in FC4 has a newer incompatible format from the previous versions. Manual dump and restoration is required if you using this database. Look at the postgres documentation for more details on this.

Reading repository metadata in from local files
This means you have too much crap in your rpmdb and it's taking a while to go through it. Check out how many kernels you have installed: rpm -q kernel kernel-smp and remove the old ones you may also try running: rpm --rebuilddb and see if it helps any. I've found that removing old kernels and rebuilding the rpmdb helped this problem.

SELinux gets messed up. I had to redownload the selinux-policy-targeted RPM from my mirror, do a forced uninstall of the old package, clean out the .rpmnew and .rpmsave files then install the new policy. Then I had to run "/sbin/fixfiles relabel" and wait. If I didn't do that, I found I couldn't log in.

If SELinux does give you problems, it can be disabled on bootup by pressing "a" on the grub bootup menu, then adding "enforcing=off" to the arguments list.

RPM complains about missing diskspace, but there is a lot free. If you are really sure your diskspace is enough, set

diskspacecheck=0
</code> in <code>/etc/yum.conf</code>.
The RPM transaction will need a lot of diskspace temporarily (much more than one might think), so be careful.
Don't forget to remove that later after the upgrade.
* Yum complains about files conflicting in the GCC package. This system was upgraded from Fedora Core 1. Remove the gcc32 package:
<pre>
sudo rpm -e gcc32

Some of your modules don't load after the upgrade. When you investigate modprobe doesn't work as expected. Run depmod:
